IMPROVEMENT IN STEAM-RADIATORS.

Specification forming part of Letters Patent No. 16 1,804, dated April 6, 1875; application iiled January 12, 1875.

To all whom it may concern:

Be it known that I, JOSHUA MASON, of Paterson, in the county ot' Passaic and State -ot' New Jersey, have invented certain new and useful Improvements in Radiators for Heating Apartments, and other purposes; and I do hereby declare that the following` is a full, clear, and exact description ot' the same, reterence being had to the accompanying drawing, forming part of this specification.

rI his invention more particularly relates t0 steam-radiators for heating apartments, and in which the air is not only heated by coming in contact with the exterior surfaces of steam or other heating tubes, but also and more effectively by its passage up and through open-ended or free and independent inner tubes, substantially in effect as described in Letters Patent issued to me VAugust 4, 1874, but with the inner and outer tubes dilierently arranged in relation to the base.

rIhe invention consists in a novel construe tion and combination of parts in a steam-radiator, composed of two or more rows of tubes, whereby effectual provision is made for drain.- age of water of condensation and for the expansion or contraction of the several rows ot' tubes free from steam.

ln the accompanying drawing, Figure l represents a longitudinal vertical section on the line w w of a steam-radiator constructed in accordance with my invention; Fig. l2, a transverse vertical section of the same, on the irregular line c Fig. 3, a horizontal sectionnon the line y y, and Fig. et a horizontal section on the line z z.

A is a lower approximately-horizontal steampipe, to which steam is admitted at its one end b. B is a similar pipe, in parallel relation, or thereabout, with the pipe A, and having an outlet, c, for water of condensation. These pipes Aand B are in communication, by hollow arms C C at reverse ends ofthe radiator, and a connecting-pipe, D, to carry off water of condensation. Mounted on the horizontal steampipe A are a series of vertical steam-tubes, E, which are connected, by upper hollow connections G, with a series of vertical steamtubes, F, mounted on the horizontal steampipe B. H and I are free or open-ended air pipes or tubes passed vertically up through the pipes A B, the tubes E F, and the upper hollow connections G. rIhese airpipes EI I are secured below to the steampipes A B by hollow corrugated nuts D, to provide for expansion.

Steam, entering at b, passes along the horizontal pipe A, up the vertical tubes E, and along the hollow upper connections G, down the vertical tubes F, and along the horizontal pipe B to the outlet c.

rIhe water ot' condensation, collecting in the pipe A from the first row ot' tubes E, passes, by the connecting-pipe D and the hollow arms G O, to the pipe B, and from thence, together with any water of condensation collecting in the pipe B, through the Outlet c. K is an air-supply box or base, on or within which the tubular radiator freely rests, with freedom to expand or contract,

and, owing to the connection, as described,

ot the lower horizontal pipes A B, by the hollow arms or connections C O, at reverse ends of the radiator and connecting-pipe D, in combination with the upper hollow connections G, strain, as produced by unequal expansion or contraction of tle inlet and outlet vertical tubes relatively to each other, is prevented from breaking the joints or otherwise damaging the structure. The airpipes I and J are in free communication with the air-supply base K, below. Air is admitted to said base either through an inlet, L,control1ed by a valve, M, when it is desired to circulate air through the pipes H I, more particularly for the purpose of Ventilating the apartment, said inlet L drawing its supply' from the atmosphere outside of the building; or air to circulate through the pipes H I may be admitted direct from the apartment, near the loor thereof, by means ofr perforated slide or other valve N controlling one or more ports, O, in the base K.

A serviceable use of such variable air-supply will be found when rst turning on the steam, or in the early use of the radiator of a morning, before the apartment is heated. It then will be advisable to close the valve M of the inlet L, and to open the valve N, until the whole air in the room is fairly heated, after which the valve N may be closed, and cold C C at reverse ends of the radiator, and the connecting-pipe D,substantial1y as and for the purposes herein set forth.

fresh air from the outside admitted by opening the valve M, to ventilate the room as Well as heat it.

I claim- JOSHUA MASON. The combination, with two or more rows of Witnesses:

steamtubes,E F, their base-pipes A B, and M. I. QUIN,
